I also have really bad inner thigh cramps.  Massaging only makes it worse.  I have found myself getting out of bed and trying to stand to hep ease the pain but the pain is so intense I just can't move and I end up lying on the floor crying.  The only thing that works for me is roll on icy hot.  I keep it at my bedside and whenever I feel a cramp coming on I use this product.  I also drink water at that time but find that the ice hot gives me the fastest relief.
